NB 12.4 Beta1, macOS, Java(TM) SE Runtime Environment 18.9 (build 11.0.10+8-LTS-162)
Unpacked NB 12.4 beta1. Started fresh no user dir, no import of settings.
Run NB, install nb-javac when requested.
Open micronaut-test, previously cloned from https://github.com/micronaut-projects/micronaut-test
I did not check the check box, trust the project in Project open dlg.
When top level project is open NB asks for Resolve problems, click Resolve, then open test-junit5, Resolve Problems step is done, subproject is open.
It looks like attached screenshot.
Performing Clean & Build on project in NB does not fix this.
Close NB, run ./gradlew build on top level project in terminal, same JDK used, it builds the project successfully.
Open the multi project in NB again, still same errors displayed. See attached screenshot and log file from this session.
In the next step I delete .gradle folder in micronaut-test, removed NB user dir, start from scratch. In Open Project dlg I checked Trust the project.
Resolve Problems dlg appears for top level project with two problems: Priming build and Trust the project. Click Resolve button, it gets green.
Then open test-junit5, Resolve Problems project appears and it is empty. Source files are open with with same errors as previously in attachment.
